BACKGROUND
The influence of demographic and anthropometric factors on nerve cross-sectional area (CSA) reference values in high-resolution ultrasound was evaluated in a prospective observational study.
METHODS
We measured CSA of median, ulnar, radial, and sural nerves in 80 healthy adults from 18 to 98 years of age. Pearson's correlation and multiple linear regression with age, gender, body mass index, and hand volume were calculated.
RESULTS
Ulnar and median nerve CSA showed a significant positive correlation with ipsilateral hand volume. Median nerve CSA in the left forearm (mean, 6.2 mm ; SD, 1.2) increased by 0.006 mm (SE = 0.002; P < .001) per cm of hand volume, resulting in a difference of 1.9 mm predictable by hand volume (mean, 326 cm ; SD, 81; range, 180-500).
CONCLUSIONS
The observed correlation of CSA and hand volume may influence the interpretation of CSA values in patients with very large or small hands.
背景
本前瞻性观察研究旨在评估在高分辨率超声中，人口统计学和人体测量因素对神经横截面积（CSA）参考值的影响。
方法
我们测量了 80 名年龄在 18 至 98 岁的健康成年人的正中神经、尺神经、桡神经和腓肠神经的 CSA。计算了 Pearson 相关系数和多元线性回归，以评估年龄、性别、体重指数和手部体积的影响。
结果
尺神经和正中神经 CSA 与同侧手部体积呈显著正相关。左前臂正中神经 CSA（平均值为 6.2mm；标准差为 1.2）在手体积每增加 1cm 时增加 0.006mm（标准误差为 0.002；P<.001），手体积可预测 1.9mm 的差异（平均值为 326cm；标准差为 81；范围为 180-500）。
结论
观察到 CSA 与手部体积的相关性可能会影响对大手或小手患者 CSA 值的解释。
